/* ERROR/WARNING messages:
E: Illegal ... command
Self-explanatory. Check the input script syntax and compare to the
documentation for the command. You can use -echo screen as a
command-line option when running LAMMPS to see the offending line.
E: Could not find compute ID for temperature bias
Self-explanatory.
E: Bias compute does not calculate temperature
The specified compute must compute temperature.
E: Bias compute does not calculate a velocity bias
The specified compute must compute a bias for temperature.
E: Cannot use both com and bias with compute temp/chunk
Self-explanatory.
E: Chunk/atom compute does not exist for compute temp/chunk
Self-explanatory.
E: Compute temp/chunk does not use chunk/atom compute
The style of the specified compute is not chunk/atom.
E: Temperature compute degrees of freedom < 0
This should not happen if you are calculating the temperature
on a valid set of atoms.
